This is a python package to make Jupyter.ipynb file a web api with json result. You can call Jupyter from Excel Formula or Ribbon CallBack Functions SourceCode in JupyterExcel

Before install, please download JupyterExcelTesting.xlsm to try its formula function and excel ribbon. If you think it works, you can modify the url in the sheet to your jupyter page and save it as "Addin" file.

This Jupyter Excel web api can be connected with Excel addin which call this web api. Excel formula will generate a web api url and through winhttp to get json result. It now works Mac Excel by using VBA-Web.
